Well you can use doge for real life usage if you are looking for a real day to day payment but many doesnt accepf it s there are others that I would like to mention. Monero and Zcash has been used in payments everyday in deepweb. They are good to use to pay someone when you are looking for anonymity. These currencies can be used for real day to day payments these days if you would like to buy in deepweb.
